R Project Updates

Updates from R Core:

• The environment variable R_MAX_VZISE can now be used to specify the maximal vector heap size. On macOS, unless specified by this environment variable, the maximal vector heap size is set to the maximum on 16GB and the available physical memory. This is to avoid having the R process killed when macOS over-commits memory.

• methods:::bind_activation() is defunct now; it typically has been unneeded for years.

• the undocumented “hidden” .__H__.cbind and .__H__.rbind are deprecated, correspondingly.

• sum(x) and sum(x1,x2,..,x<N>) with many or long logical and integer vectors no longer overflows (and returns NA with a warning), but returns double numbers now in such cases.

• Single components of POSIXlt objects can now be extracted and replaced via [ indexing with 2 indices.

• S3 method lookup now searches the namespace registry after the top level environment of the calling environment.

Three major misconceptions I've heard about #rstats this morning:

1) No one over the age of 30 can learn how to use R

2) R is kind of cult-y

3) People who use R like to show off
